Health, Society, and Noise Pollution

Does Noise Pollution Have Physical Effects on the Human Body?

Yes. Many global health agencies and non-governmental organizations recognize noise pollution and its harmful effects. These include the World Health Organization (WHO), the United Nations, the Environmental Protection Agency (EPA), and the National Institutes of Health (NIH).

According to the WHO report titled Guidelines for Community Noise, there are seven categories of adverse health effects associated with noise pollution:

1. Hearing impairment
2. Interference with spoken communication
3. Sleep disturbances
4. Cardiovascular disturbances
5. Mental health disturbances
6. Impaired task performance
7. Negative social behavior and annoyance reactions

According to the NIH, more than 10 million people in the United States suffer from permanent, noise-induced hearing loss.

1. Can you describe an incident in your life when you were affected by noise that was annoying or painful?
2. Have you ever been awakened in the middle of the night by noise outside your home?

Why Has Noise Pollution Become So Prevalent in Society?

Noise pollution results from several factors, including the economic interests of business and industry, government inaction in providing adequate protection for citizens, and individuals who create or tolerate excessive noise.

There are three common forms of bias encountered in noise pollution issues.

1. Social bias. Noise pollution is often framed as a lifestyle issue rather than a public health concern. It is commonly assumed that only a small number of people are affected or bothered by noise.
2. Economic bias. Individuals or businesses may refuse to acknowledge a noise problem because mitigating or eliminating it would require time, effort, or financial cost.
3. Bureaucratic bias. When public officials claim they are “doing everything we can” without providing measurable actions or timelines, the focus often shifts toward managing complaints rather than reducing noise.

In many conflicts between two parties, there is often a hidden third party. Disputes between neighbors are frequently driven by noisy products, while the industries that manufacture and sell them profit quietly and assume little or no responsibility.

1. Below are some common expressions and attitudes about noise pollution. What inherent bias is present in each statement?

“If it’s too loud, you’re too old.”
“Noise equals prosperity.”
“No one else is complaining about the noise except you.”
“You must have overly sensitive hearing.”

What Is Society Doing About Noise Pollution?

In 1972, the U.S. Congress enacted the Noise Control Act (NCA), declaring it national policy to promote an environment free from noise that jeopardizes public health and welfare.

Following the enactment of the NCA, the Environmental Protection Agency (EPA) created the Office of Noise Abatement and Control (ONAC).

The role of ONAC was to establish noise emission standards, implement product labeling, coordinate federal noise reduction programs, and assist state and local noise control efforts.

Ten years later, ONAC lost its funding.

Today, noise regulation falls under the jurisdiction of state and local agencies. Because communities set their own noise codes and enforcement policies, responses to similar noise complaints can vary widely across the country.

1. Should noise codes and enforcement be the same everywhere, or should communities set their own standards?

Communities across the United States have enacted laws to limit excessive noise from various sources. In recent years, increased legislation and enforcement efforts have aimed to reduce noise exposure.

As media coverage of noise-related health effects has increased, more people are recognizing that noise pollution is not merely an annoyance.

In the past, many consumer products were intentionally designed to be loud to imply greater power. Today, household and office products such as vacuum cleaners, dishwashers, and computer equipment are significantly quieter.

Many homeowners choose quiet push-reel or electric lawn mowers, which reduce noise and environmental impact. In response to noise complaints, some communities have restricted or banned the use of leaf blowers.

1. As a consumer, what quieter products would you like to see on the market?
2. Should products be banned or restricted because of noise emissions?
3. What negative social effects result from noise pollution?

How Does Loud Sound Affect Driver Awareness?

The National Highway Traffic Safety Administration (NHTSA) estimates that approximately 25 percent of vehicle accidents involve driver distraction.

Drivers experience slower reaction times when listening to loud music or adjusting car stereo controls. Loud in-car sound can reduce a driver’s ability to hear pedestrians, other vehicles, and important environmental cues.

This includes emergency vehicles such as police cars, ambulances, and fire trucks.

What Negative Social Effects Result From Noise Pollution?

Economic effects of noise pollution include reduced property values in affected communities, medical costs related to hearing loss, and emotional and physical stress for those exposed to chronic noise.

Additional law enforcement resources are often required to enforce existing noise codes and protect residents.

Workers may experience reduced productivity, increased health costs, and absenteeism when exposed to excessive noise at home or in the workplace without proper mitigation or abatement.

2. Are all noise pollution problems the same?

Are All Noise Pollution Problems the Same?

No. Common sources of noise include boom cars, car alarms, motorcycles, and vehicles with loud exhaust systems. Other frequent sources include barking dogs, leaf blowers, and construction activity.

1. If your next-door neighbor had a barking dog keeping you awake at night, how would you attempt to negotiate a solution?
2. Does the noise from one loud motorcycle present the same issues as the noise from one hundred loud motorcycles?

Car alarms are a common source of urban noise pollution. Some alarms use audible status indicators that activate whenever there is external vibration or sound.

Despite their noise, there is little evidence that car alarms effectively deter theft. In many cases, thieves intentionally trigger alarms to mask the sound of breaking glass. Most people do not respond to car alarms, yet the noise disrupts classrooms, homes, workplaces, and public events such as weddings, funerals, and celebrations.
